IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent N0. 88,951, dated April 13,1869.

To all lwhom it may concern: y Beit known that I, AMAsA FooT, ofEarlville, in the county of La Salle and State of' Illinois, haveinvented a new and useful Improvement in Reaping and Mowing Machines, ofwhich the following is a full, clear, and eX- act description, referencebeing had to the accompanying drawing, making a part of thisspecication, in which- A is a frame of usual form. B is the groimd ordriving wheel, the shaft O of which is mounted in boxes D D, bolted tothe frame A. E is an internal gear-wheel made fast to the arms of theground-wheel B by means of screwbolts.

Thus far the machine is constructed like other machines of the kind nowin use.

F is a spur-pinion on shaft G, of usual form except that it is longer7to permit an endwise movement without being thrown out of gear withinternal gear-wheel E, the arms of the ground-wheel being cut away, soas not to interfere with said pinion when moved in so as to face on theoutside with internal gear-wheel E. H I are two bevel-wheels onpinion-shaft Gr, which has its bearings in the boxes J K, bolted fast tothe frame A. L M are two beveled pinions on crank-shaft N, which has itsbearings inthe boxes O and I,'made fast to the frame by means of bolts.Q is a crank to which the pitman is attached, said pitman bein'g alsoattached to the sickle or cutting bar in the usual manner.

By means of a lever, S, the shaft G, with the pinion F and beveledwheels H I, is moved toward the ground-wheel to throw the beveled wheelH out of gear with pinion L, and at the same time, if desired, to throwthe beveled wheel I in gear with the pinion M 5 or the lever may beretained in a central position on the pin T, and both beveled wheels vIIand I will be thrown out of gear. VThe object of this arrangement is tocombine in one machine the dierent motions of the sickle necessary forthe cutting of both grain and grass, or to the varying condition ofeither, and thus to fully secure the objects of a combined reaper andmower. y

When cutting standing grain, the adjustment isnsuch as to place thebevel-wheel H in gear with pinion L, thereby giving a motion to thesickle suitable for cutting standing grain; and when cutting lodged ortangled grain or grass, by means of the lever S the bevel-Wheel II ismoved out of gear with pinion L, and at the same time bevel-wheel I isthrown into gear with pinion M, thus giving a much quicker motion to thesickle, and adapting it to the work required of it. A

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

l. Two driving gears oi' unequal size, in combination with two pinionsfor varying the speed of vibration of the cutters.

2. Rotating the crank-.shaft by either one of two in dependenteoncentriebevel drivinggears of unequal size.

3. Two bevel-pinions on the crank-shaft, arranged outside of thejournal-bearing of said shaft.
